In order that the invention may be well understood, an embodiment thereof, which is given by way of example only, will now be described with reference to the drawings in which:
Referring to
The front wall 18 of the base portion 14 has a notch 20 formed in its upper edge for receiving a front portion, or lip, 22 of a module 24 (best seen in
Referring to
The module 24 is push-fit mounted in the base portion 14 of the housing to permit quick and easy fitting and removal. The underside of the rear of the base wall 28 is provided with two lugs 32, only one of which can be seen in
Towards the front end of the module 24, a steel pin 36 is fixed to the underside of the base wall 28. The steel pin 36 extends across the width of the module 24 and projects beyond adjacent side portions of the module such that its ends can engage in respective recesses 38 that are fixed in the base portion 14 of the housing adjacent the sidewalls 40 of the base portion. The engagement of the steel pin 36 in the recesses 38 locates the front end of the module 24 in the housing. The recesses 38 are arranged such that once the lugs 32 have been snap-fitted onto the pins 34, the front end of the module 24 can be pushed down into the base portion 14 to bring the ends of the steel pin 36 into engagement with the recesses. This allows the module 24 to be quickly and easily fitted into and removed from the base portion 14.
The recesses 38 may be formed directly in the base portion 14 or in a separate member, or members, 42 that is/are fixed in the base portion. Whichever arrangement is used, the material may be a suitably resilient plastics material and the recesses 38 formed such that the ends of the steel pin 36 snap-fit into the recesses to provide rapid securing of the module 24 to the base portion 14 of the housing.
The base wall 28 of the module 24 is formed with an elongate rectangular aperture 44 that extends in the lengthways direction of the module. The aperture 44 is configured to receive the upper portion of a ticket transport device 46 (
Approximately midway along its length, the base wall 28 is formed with opposed recesses that house respective read devices 48 for reading data from the magnetic stripe of a boarding pass inserted into the transportation ticket reading apparatus 10. The read devices 48 are positioned in opposed spaced apart relation on opposite sides of the aperture 44 such that as long as a boarding pass is inserted into the aperture 26 with its magnetic stripe facing the base wall 28 of the module, it does not matter which end of the boarding pass is inserted first as the magnetic stripe will pass over one or the other of the read devices.
The base wall 28 of the module 22 is also provided with a recess 50 that houses a first sensor. The recess is positioned such that the first sensor can detect the insertion of a boarding pass into the transportation ticket reading apparatus 10. A second sensor is housed in a recess 52 formed towards the rear of the base wall 28. Signals from the first sensor are used to trigger start-up of the ticket transport device 46 to cause a boarding pass inserted into the insertion aperture 26 to be moved further into the transportation ticket apparatus 10 and a signal from the second sensor is used to determine that the boarding pass is fully inserted into the apparatus so that the ticket transport device 46 can be switched off while the data read from the magnetic stripe is processed.
The wiring from the read devices 48 and the sensors located in the recesses 50, 52 runs along the underside of the base wall 28 of the module 24 and is fed into a common plug 54. The plug 54 plugs into a socket 56 that is connected to a wiring loom in the base portion 14 of the housing. Thus, the electrical connection between the module 24 and the apparatus 10 can be rapidly made and disconnected by one simple operation.
The ticket transport device 46 comprises an endless belt 58 that can be made of any suitable polymer material. The endless belt 58 is fitted onto two rollers 60, one of which is driven by a suitable electric motor via gearing (neither of which are shown). The rollers 60 are cantilever mounted on respective pins 62 that are secured to a sidewall 40 of the base portion 14 of the housing or to a suitable chassis member fixed adjacent the sidewall. A center span support 64 for the endless belt 58 is positioned between the rollers 60 and is cantilever mounted on pins 66 in the same way as the rollers. The center span support 64 comprises a box like structure that provides support for a plurality of idler rollers (not show) that support the underside of the upper bout of the endless belt 58. As will be explained in more detail below, the cantilever support of the rollers 60 and center span support 64 permits rapid belt replacement.
The ticket transport device 46 further comprises idler rollers 68 (only one of which is shown in
Referring to
In use, if the read devices 48 or the sensors housed in the recesses 50, 52 are damaged or worn, or material is jammed between elements of the ticket transport device 46 and the module 24, the problem can be quickly and easily rectified on site. First the lid 16 of the housing is pivoted to the open position shown in
It will be appreciated that the module 24 can be removed from the transportation ticket reading apparatus 10 by three simple pulling operations to permit replacement or the removal of jammed material. Similarly, reinstatement is achieved by three simple push-fit operations.
If the endless belt 58 is worn or damaged, once the module 24 has been separated from the housing (electrical disconnection may not be necessary), the cantilever support of the rollers 60 and center span support 64 allows the belt to be slid off of the rollers by a simple transverse movement in the direction of the arrow 72 (see
It will be understood that while in the embodiment it is preferred that the module 24 is removed from the transportation ticket reading apparatus 10 when changing the endless belt, this is not essential. Depending on the configuration of the apparatus, it may be sufficient to pivot the module away from the ticket transport device.
It will be appreciated that the components of the transportation ticketing read apparatus 10 that are most likely to be damaged or worn can be quickly and easily replaced and jammed material can be readily removed from the apparatus without a time consuming strip down of the apparatus and that this can be accomplished on site by unskilled operatives.
Although not shown, it will be appreciated that the transportation ticket reading apparatus 10 and/or the module 24 may be provided with means for securing the module in its mounted position additional to or as an alternative to snap-fitting of the lugs 32 and ends of the steel bar 36 with the mounting pins 34 and recesses 38. The securing means would preferably comprise a quick release device, for example a suitably arranged rotatable camming device could be used.
It will be appreciated that the lid 16 does not have to be pivot connected to the base portion 14 of the housing; it could simply lift off. It will also be appreciated that the benefit of quick removal and replacement of the module 24 may be obtained by providing the housing with a portion that can be moved to provide sufficient access to the module to allow it to be pulled from its mounted position and pushed back to its mounted position.
It will be appreciated that the steel bars 36 and 76 could be replaced by respective pairs of members for engaging in the recesses 38, 76. However, using a single steel bar in each case provides a more rigid structure with less likelihood of twisting of the respective part or of one side not properly locating in the respective recess.
No detailed description has been provided of the read devices 48 or of the sensors to be housed in the recesses 50, 52. In each case, any suitable read device/sensor may be used and since these are things that will be familiar to the skilled person, no further mention will be made of them here.
It will be understood that signals received from the read devices 48 and/or the sensors housed in the recesses 50, 52 may be processed within the transportation ticket reading apparatus 10 or transmitted by any suitable means for processing in another apparatus. These are matters that will be familiar to those skilled in the art and so will no further mention will be made of them.
The transportation ticket reading apparatus may be arranged to send valid tickets out through a designated exit aperture or back through the insertion aperture 26. Similarly, rejected tickets may be sent through a designated exit aperture or back through the insertion aperture. Again, these are matters that will be familiar to those skilled in the art and so no further mention will be made of them.
